\n" ); document.write( "My real question is do I use the answer of the population in 5 years in the problem y=a (1-r)^t to get the answer of the population in 10 years or do I subsitute 3000 for a in both problems?

You can put this solution on YOUR website!
Yes, you can use that equation for the town's population. y is population at time 0, and t is time in years. r is the PERCENT DECREASE, and it should be as a decimal. a is the initial population at t=0. Notice that you are using $\"1-r\"$ , which is the factor giving how much population quantity the town RETAINS each year.\r

\n" ); document.write( "More specifically, your case is $\"y=3000%280.99%29%5Et\"$ . \n" ); document.write( "
